Abstract: Statistical thermodynamics and spectroscopy have been combined to evaluate thermodynamical quantities of tin chalcogenides (SnO, SnS, SnSe and SnTe). Their temperature dependence has been studied in the temperature range 100-2200K. The authenticity of data is established by the comparison of reported values. Discrepancies between calculated values and observed values can mainly be attributed to contributions from excited electronic states.
